We're dividing 938348 by 3 
The aim is to understand the frequency of 3 in 938348.

Advancing to step 1:
3 goes into 9 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

Let's proceed to step 2:
3 divided by 3 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 3 from 3, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Going ahead to step 3:
3 goes into 8 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 312.0
Subtract 6 from 8 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Moving on to step 4:
If we divide 23 by 3, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 3127.0
The remainder is 2 after subtracting 21 from 23.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Moving on to step 5:
When dividing 24 by 3, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 31278.0
Deduct 24 from 24 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Step 6:
8 divided by 3 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 312782.0
Subtracting 6 from 8 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 312782.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 312782.66
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 312782.66 and a remainder of 0.002.
